Drawn from over fifteen years of peer-reviewed essays and national design awards published by the Association of Collegiate Schools of Architecture (ACSA), this volume presents the discipline's best thinking on sustainability in written, drawn, and built form. Providing a primer on sustainability, useful to teachers and students alike, the selected essays address a broad range of issues. Combined with design projects that highlight issues holistically, they promote an understanding of the principles of sustainability and further the integration of sustainable methods into architectural projects. Using essays that alternately revise and clarify twentieth century architectural thinking, "The Green Braid" places sustainability at the centre of excellent architectural design. No other volume addresses sustainability within the context of architectural history, theory, pedagogy, and design, making this book an ideal source for architects in framing their practices, and therefore their architectural production, in a sustainable manner.
